摘要： 目的 调查武汉地区高校大学生的体力活动现状,比较男生与女生以及理科生和文科生体力活动之间的差异,为制订大学生有关的健康促进策略,提高其体质健康水平提供支持.方法 采用IPAQ长卷对武汉地区5所高校1920名大学生进行调查,其中男生1011人,女生909人;理科生983人,文科生937人.结果 在体力活动类型方面,家务类男生显著低于女生,体育休闲类男性显著高于女生.在体力活动强度方面,男生在中高强度和总量方面均高于女生.在日常体力活动量等级方面,低强度体力活动比例较高,约16.4％.武汉地区大学生的每周静坐时间和睡眠时间占了每天总时间的54.0％,平均每天运动时间不足半小时,男生体育锻炼时间显著高于女生.上述各方面,理科生同文科生都无差异.结论 武汉大学生的体力活动以中等强度活动为主,高强度活动量较少,低强度活动比例较高,大多数女生没有每天锻炼的习惯.有关部门应该更多关注武汉大学生的体力活动,强调增强大学生体力活动意识,逐渐养成终身运动的习惯,提高体质健康水平.

摘要： 本文为探讨体力活动与健康之间的关系，调查了呼市地区部分成年人身体健康状况及体力活动的基本情况，发现中等体力活动水平的人数相对较多，占总人数48.5%，而高体力活动水平和低体力活动水平人数都相对较少，分别占总人数的32.0%和19.3%；另外受试者随着体力活动水平的增高，身体质量指数(BMI)、腰臀比(WHR)、收缩压(SBP)、舒张压(DBP)及血糖(GLU)都呈现下降趋势，说明体力活动水平越高，健康水平越高。因此，在本研究中呼市地区部分成年人随着体力活动水平的降低，肥胖、高血压及糖尿病发病风险均增加。

摘要： 目的:调查江苏省各地区人群体力活动量现状并对其特征进行研究分析。方法:采用国际体力活动短问卷在省内104个县/区按照PPS抽样原则进行抽样调查。结果:江苏省常住人口的体力活动水平高度活跃率为40.9%;男性高度活跃率为43.0%,女性为38.6%,男性每周总体力活动量、每日MVPA时间高于女性,男女间差异显著(p<0.01);20-39岁年龄组高度活跃率为36.8%,40-59岁年龄组为45.6%;站立走动为主人群的体力活动水平高度活跃率最高(51.4%),但是该人群的经常锻炼人群比例最低(16.4%);城镇人群的高度活跃率低于农村人群,但是经常锻炼人口比例高于农村人群;学历高的人群体力活动水平高度活跃率低,但是经常锻炼人口比例较高。结论:1江苏省常住人口的体力活动高度活跃率为40.9%,低于我国上海地区,也低于主要发达国家的水平;2江苏男性的体力活动水平高于女性,40岁以后的成年人体力活动水平高于年轻人群,农村人群体力活动水平高于城镇人群;3本研究还发现,与工作方式相关的体力活动量对日常体力活动量的影响较大,体重超重人群表现出更加强烈的锻炼积极性。

摘要： The paper expatiates on the week physical activity of the middle school students from the perspectives of physical activity concept, application of IPAQ, developing trend of physical activity of middle school students in China and the world, comparison between IPAQ and the life style of the Chinese middle school students and the physical activity of the middle school students monitored by IPAQ. The paper points out that the monitoring has great application future.%从体力活动的概念及IPAQ的相关应用、国内中学生体力活动流行趋势、IPAQ与国内中学生生活方式对比研究、IPAQ监测中学生体力活动的注意事项等几个方面，对与中学生周体力活动量的相关问题进行了阐述，表明对中学生进行体力活动监控具有良好的应用前景。

摘要： Demographic effects (sex and parenthood status) on the level of association between self-reported and accelerometer assessed physical activity were examined among a large diverse sample of adults. Participants (N = 1,249, aged 20 - 65 years) wore accelerometers (Actical) for 7 days and completed an interviewer-administered physical activity recall questionnaire (IPAQ- LF) for the same period. Mean daily minutes of moderate physical activity (MPA) and moderate to vigorous physical activity (MVPA) were used in analyses. Linearity between methods was explored by regressing mean minutes of activity and Pearson’s correlations were performed. A weak association between IPAQ-LF and Actical minutes of MPA and MVPA per day was shown for the whole sample (rs = 0.216 – 0.260). The magnitude of association varied between males (rs = 0.265 – 0.366) and females (rs = 0.124 – 0.167), although no obvious variations in associations were evident for parenting status. The IPAQ-LF produced substantially greater variations in estimates of physical activity than that recorded by the Actical accelerometer and large discrepancies between methods were observed at an individual level. Self-report tools provide a poor proxy of overall human movement, particularly among females. Inferences made at an individual level from self-reported data, such as intervention efficacy or health outcomes, may have substantial error.
